Thisl invention relates yto internal combus ,tlonfengines' and morevspeelficallyf to means It isV an. object'ofthis iny'entionto provide more eicientf'means for 'cooling internal combustion engines andinore lspeciically f to ,l

provide a means whereby y.cooling water iswdelivered? directly from fthe radiatorito lthe cylindei'ihead-ofitheengine xi f 5 Other objectsiof the invention will be oblViens-from the following ,description of the preferred embodiment of my invention which is-,illustrated in thezaccompanying drawings, Vin whichz:` f i Figurel is a somewhat diagrammatic View of the.: radiator,. engine and transmission` of lanFautomotiveV vehicle ,showiiig'` the water connections between A the;` radiator and vthe engine head1V f n Figure 2aisV a cross fsec'tion onthe line" 2 2 Of Figure gi' "di i s ff Figure 3 is a View of the cylinderfhead water-jacket, mainly in .top plan `and partly insection on the line 3"-f3 of Figure 2. v

j In the drawings the reference character' indicates the radiatorn the engine and 7 the i transmission'uofan automobile. i

The engine -6 is of the singlei sleeve valve '.typeand includes a block Shavingjtherein a plurality ,ofi cylinders which are Water jacketed,jasgindicated :at2 9, a sleeve Valve 10 -niovable Linv each. cylinder,

'and' a ,piston 11 movableineach sleeve.y v

A 'Thesreference f'character 12 indicates the cylinder head which "is securedtothe cylinder block/8 by bolts, such as 20, and which has a A of and extendingupwardjly from the lower endet the cylindricalypjortion 13 is "a; hollow conical portionll whichi's internally threaded at its upper fend for the reception of the i spark plug 15. i "Asis Aclearly shown'V in Figure 2, there isa space between thecylinl drical portion 13 and the conical portions-111 for'coolingwater. l The cylinder headcover plate 17 hask openings 18 into which the upper ends 'of the Ybetween the conicalportion ofthe cylinder "As maybe seen from the drawing, there are two separated channels in the cover plate, one, 21, for the water entering the water jacket and wall 23 'beneath eachV opening 24 lis a ffunnel 25 with its spout projecting into the space 16.v I ater enters the channel 21 in the cover Vplate at26directly from they pump 32.7 In

50. conical portions'lt fit. The outer edgesof the i lcover kplateare 1 secured to theV cylinder block *byboltssuchlas 19.` Thejoints between the f-r cylinderhead and the cylinder block, between l the-"cover plate and the cylinder blocl,= and-s Y v.head and the cover plate are all made waterproof. Y

order to prevent ythe water tromaflowing*V `.through the water jacket without passing throughV the hollow spaces -16inj the depending kportions of ftheY cylinderhead the channels 21 and 22 are separated by partitions 28 andv 28. Since these 'partitions vprevent the water going directly fromthe channel21 to 'Y the channel 22,'in order to get out of the water 'j acket,'the water must flow, through the openings 24, into the tunnels 25, which direct il into the spaces 16 whereit cools the depend--A ing portions-of the cylinder head. From the .30 which returns it to the radiator.4

' As shown in Figure 1 thefcooling water for the cylinder headis drawn directlyirom` the bottom of the radiator 5Y through thepipe Y 31 by the pump 32 which-,is driven bythe fan lspace 16-the water flows into .the vchannel 22 out ofthe' water jacket at 29into the pi-pe SLS shaft The pump forces the water into the cylinder' head water j aclret at 2G through which it flows and is returned to the top of the radiator as described above.

It is well known that the portions of the cylinder head directly above the pistons are heated more and raised to a higher temperature than any other part of the engine. Since in my cooling system the water for cooling these portions is drawn from the bottoni of the radiatorwhere it is cooles` `l rpinnpod directly to the cylinder head vWater ack-et where the funnels 25 direct it into the hollow portions of the cylinder head which de pend into the cylinder, my system is very ellicient in cooling these portions of the engine. It is to be understood that the cylinder block can be cooled in any ordinary or desired Inanner. Y

Though my cooling means has been shown and described in connection with thecylinder head cfa sleeve valve Iengine i-t may e lused elsewhere and my invention is limited in scope only bythe appended claims.

Y I claim:

2. In an engine having a. cylinder and la cylinder head having a hollow portion :projecting into :the cylinder, a cover plate for the cylinder head having therein a conduit having means, including a funnel, to direct cooling fluid directly into said hol-low portion, said cover plate also havinga channel for conductingthe fluid from the hollow port-ion of lthe cylinder head, and means to prevent passage 4oaf the :fluid from the `conduit -to the channel wit-hout passing through the hollow portion.

3. "In an engine :headcooling system., means Y to condnct cooling fluid directly to .said cylinder head, and means to direct said -fluid directzly on the portion of said head which :is directly above the piston.

4. A cover plate having fluidinlet'and discharge channels, said inlet channel having a lower wall having perforations therein at inllervals, and means adjacent said perforatio'ns lo direct cooling lluid to the portion of the cylinder head directly above each cylinder.
